"There must be an outlet on the other side, though," replied Melton. "All we need do is to paddle across and find it."

"But which is the proper side?" said Canaris. "Are we headed straight now?"

"By Jove, I don't believe we are," replied Guy. "I'm afraid we are completely mixed up. We will paddle until we reach the shore, and then follow it till we come to the outlet."

"Yes, that will do very well," said the colonel. "The lake cannot be so very large. I wish we had time to complete a survey of it. I should like to make a report to the Royal Geographical Society."

"I wish the honorable members of the R. G. S. could change places with us," said Sir Arthur, with a groan. "I have no doubt some of those lunatics would enjoy this beastly hole. There is no accounting for taste, Carrington."

The colonel made no reply. He was keeping stroke with Chutney's paddle, sharing with him the outlook ahead. The minutes passed on, but still no signs of any shore.

"It's a pretty fair-sized lake after all," said Guy.

"And we are the first white men to navigate its waters," remarked the colonel solemnly. "This is a wonderful discovery. Our fame as great explorers will be assured if we ever get back to England."

"Land ahead!" shouted Guy suddenly, and snatching the torch from Sir Arthur, he stood erect as the canoe shot gently toward a dim object that rose from the gloom twenty yards distant. Amid breathless silence the keel nicked the sandy beach and Guy sprang out.

One brief second he held the flaming torch aloft.
